Dear All,

As per title, is it advisable to delete MAF sensor and use 3 BAR MAP sensor to handle the 1JZGTE VVTI. What i've gathered is with MAP sensor, we can manage the AFR more accurately and tuning for more powaaaahhh will be easier in future.

I have been offered of a Greddy Emanage Blue + Boost Pressure Sensor (not sure same with MAP sensor or not) to get the job done. Before i get into wild things like this, please share some inputs.

Thanks,
Ken

power yes, but im not sure if altitude will have any affect.

Anyway, I wont go for emanage, straight go for standalone. Can your ecu remap?
No the ECU can’t be remapped, i don’t want any complicated job so i am opting for piggyback only. I want to optmize the AFR and possibly increase a little boost on turbo, target HP is 350 at the crank. However some guys said it’s not needed to convert to MAP if i am not boosting over 500hp.

Thanks,
Ken

tuning with map sensor alone means going for speed density tuning...

and the fact it will be handled by emanage blue.. that is notorious for being faulty/clone or lost its tune out of nowhere.....

i suggest u keep the stock ecu tune...unless u were going with higher and better standalone ecu....


and with the nature of tuner in malaysia way of tuning, u can expect losing on fuel consumption, smooth driving and likely smooth idling that is on stock ecu....


trust me...if u were not going to mod the engine all out, keeping it stock tune by stock ecu is a much better option for road car.....

I am not looking at crazy power upgrades (YET) but wanted to optimize the AFR. I had modified all the, exhaust, downpipe, intake and intercooler pipings when converting the engine in a E46 chassis and i am pretty the air flow measurement is slightly off compare to stock tubes. My gut feelings telling me that the current engine performance is not optimal yet. Idling may be stable but during drive, the acceleration is kinda off as i am expecting even stronger pull.

I have 2 options now, Unichip Q and Emanage Blue, obviously Emanage blue is not everybody's favorite so i will pass on that. What do you guys think of Unichip ? Last time there was this RS Tune used to tune Unichip in Puchong.

Thanks,
Ken

im not saying that u cant use emanage blue... just that device capability not worth going to map sensor based...unless the tuner is definately able to smooth things out on every driving occasion...

Hey you think we could meet up one day and let me sit in your car for comparisons sake? You're running on stock turbo right?

Yup sure, however weekends only i am available.

Edit: still using stock turbo and manifold, only modified down pipe.

@Mitevo7 come join us la.
This date i can't, family dinner, next one lar, and also give me more time to tidy up the car too, got some loose brackets somewhere, tak tak tak tak tak like something rattling in the engine bay.

Thanks,
Ken

If my target is 350whp, without going MAP conversion, can the emanage BLUE able to do it?

I doubt you can get that number without a turbo upgrade. My setup had a single large turbo standalone ECU setup to get 360whp with lots of supporting mods (top feed injectors, fuel pump upgrade, injector upgrade, etc etc)

My plan is to hi-flow the CT15B, standard boost at 0.9 bar, scramble boost at 1.4 bar to get to 350whp when required. The modder’s suggestion to me, larger fuel injector, better ignition, spark plugs, after market BOV to get to that numbers.

Feasible ?

Ken

Are your current injectors side-feed? If so the mod will require a fuel rail and top feed injectors. Ignition coils no need to upgrade as stock is already quite good unless yours is worn out and get a GFB or an ori Turbosmart BOV. Those are awesome.

As for scramble boost I'm not a fan as I believe it kills the turbo much faster. But if modders have done it safely and worked well for them then yeah why not? But just be warned that pushing anything above it's maximum state is not going to do it favors.

Stock everything down to stock BOV. I need recirculating BOV setup, otherwise loose power and idles like shit.

The scramble boost will be done only i modified the CT15B with steel fin. The stock ceramic fin is weak.

As many upgrade you do, the engine still in stock mode iinm. Keep it that way for a moment. Correct me if i'm wrong.
Calm down and plan lah, have a kit kat.
Modder can tell u this and that. Anyway you the final decider....lol :biggrin:

That's the beauty of stock 1JZ, bolt on mods can have so many effects on it. Just checked again myself, if i am not running over 500hp MAP sensor is pretty much unnecessary. I will change title to Prefered Piggyback ECU for 1JZGTE VVTI.

Ken

Done. (the rename)

There isn't a lot of piggybacks out there for you to choose that can handle 6-cylinder. Personally I'm not a fan of the piggyback only because I've seen what standalone can do and the pricing whilst more expensive, makes it more worthwhile in comparison.

Thanks dude ! Reason i am routing for Piggyback for now is because there were 2 ready for me to install at very fair price. Emanage Blue and Unichip Q. For Unichip Q to perform better, i just need to buy another turbo module. My questions now are:

1.) Which one has more "Know How" people in the market to tune
2.) Which one performs better when i decided to go beyond 350whp
3.) Which one is easily removed so that i can go for standalone, if i have the money :biggrin:

Thanks,
Ken

Why would the BOV affect idle?

1. both Unichip and Emanage have huge support in KL. Both have huge followings.
2. both work. Unichip will need that module. EManage however I'd recommend you go higher end like Ultimate.
3. both will need to splice your original wires so switching to standalone might be messy

Stock 1jzgte VVTI uses recirculated BOV setup. The HKS SSQV that i had is vent to
atmosphere setup, and since i am still using MAF setup, the vented air will cause the engine to run rich.

Maybe you can get hks ssqv adapter to recirculate the air instead get another bov. Got sell.

But during idling the BOV is closed? Do you mean idle immediately after release throttle?

Hi Izso,

I am not interested to switch to standalone, wanted a more plug and play type of solutions. Think i am getting the unichip since i had seen more people reviewed that its good things compared to Emanage. Emanage has notorious reputation of being called E-damage.

Thanks,
Ken

Yes i knew that, therefore later on i will research on ideal positions to mount the SSQV to reduce the use of long hoses.

Idle immediately after release throttle, there were few times the engine almost stalled upon releasing pressure.

I had that issue once, but I think my mechanic just did some tuning. Still having my BOV vent out....:driver:

You running 1 bar boost, of course you need special tuning hahaha !
No lah, mine stock boost 0.6 only. Got one time vacuum hose came off, boost at 1 plus bar, idling no issue also, but acceleration very shoik......hhahahhahahhaha

I think for auto transmission, recirculating BOV is more suitable due to we don't need to lift off throttle to change gears, we are staying constantly on boost. As for manual, dump valve is more relevant.
